Hi Shahid.
Not sure how you got this question through to me, since I no longer answer questions at all experts, but I will try to help.

I have noticed this, too, and I just considered it a bug. One workaround is to make a COPY of the document first so that you are not working on the original, select everything, choose Object "rasterize", then try your Export.

Let me know if it works?

Also, please take a look at this, it might help you?

I can help troubleshoot your Illustrator 9 through CS3 (and most CS4) problems and suggest the best way to get the results you need. Although I can help with some installation issues, my forte is prepress and how to use the tools and functions in the application itself.
